One object of the present invention is to construct a device in which the spinning and subsequent winding of the spun fibers is accomplished in a single device.

A further object of the present invention is to construct such a device from relativelyfew and simple parts which will perform trouble free over an extended period of time and which can be manufactured at a reasonable cost.

It is another object of the present invention to'construct such a device so that it can be rotated at high speeds and can 'be operated with'great efliciency.

With the above objects in view, the present invention consists in a spinning and winding device comprisingga support, a bell-shaped member mounted for rotation aboutthe longitudinal axis thereof on thesupport, t'he bell-- shaped member having an inner surface flaring from one end of the bell-shaped member to the other end thereof and being formed at the one end thereof with an axial opening,- air-outlet means in the region of the other end of the bell-shaped member, a stem-shaped deflecting member fixedly attached. to the bell-shaped member projecting inside the bell-shaped member from the other end thereof in axial direction towards the one end of the bellshaped member spaced from the inner-surfa'oethereof, the projecting tip of the stem-shaped deflecting member being located opposite the axial opening-spaced a small distance from the inner surface of the'Fbell-shaped member, and,

driving means operatively connected to the bell-shaped member for rotating the same about the axis.

The novel features which are considered'as characteristic for the invention are set forth in particular in the" Referring now to the drawings in which the device is shown in a front view and in a section taken alongthe longitudinal axis of the device, the spinningand winding device basically consists in a substantially cylindrical housing having a longitudinal axis, a bell-shaped membar 12 mounted for rotation about the longitudinalaxis in the housing, a deflecting member 14 fixedly attached to the bell-shaped member 12 and drive means 16, shown in the drawing as electric motor, forrotating the bellshaped member 12 about the longitudinal axis.

The bell-shaped member 12 'has an inner surface 18 flaring from the upper end 20of' the bell shaped'mein- 2,842,933 Patented July 15, 1958' ice her to the lowerend 22'. The upper end 20 of the bellshaped member is formed with a flaring axial opening 24 therethrough. Fixedly attached to the upper end 20 of the bell-shaped member is an elongated tubular member 26, the lower open end 26' of which communicates and blends into the axial opening 24 in the upper end 20 of the bell-shaped member. The upper open end 26 of the tubular member is preferably bell-mouthed. The lower endof the elongated tubular member 26 is screwed in the upper endZii of the 'bell-shape-d'rnember 12 as clearly shown in Fig. 2, but the connection between these two members can also 'be made in any other convenient manner.

A plurality of spaced, preferably round small radial openings 28 are formed through the bell-shaped member in a plane normal to its axis and adjacent to its bottom end 22.

The above mentioned deflecting member 14 consists of a plate-shaped portion 30, and an elongated sternshaped portion 32 projecting from the plate-shaped portion 36 inside the bell-shaped member 12 in the direction of theaxis of the bell-shaped member, towards the upper end 20 of the member 12, and the spherically shaped tip 32' of the portion 32 is spaced a small distance from the upper end 20 of the bel-l-shaped'member to form 'withthe same a streamlined annular guide channel. The. plateshaped portion of the deflecting member and the stemshaped portion thereof are preferably made from two parts for easier manufacturing, and these'two parts may be soldered or welded together or connected together in any other convenient manner. The plate-shaped portion 30 is preferably made with a central hollow boss 30 and a peripheral flange 3E)".

The lower end of the :bellsha-ped member 12 is preferably provided with an internal screw thread and the flange 30" is provided with an external screwthread so' that'the plate-shaped portion 30 of the deflecting m'ember 14 may be screwed into the open bottom end of the bell-shaped member 12 to close the same. A stud shaft 3'4is mounted in the hollow boss 30' of the deflecting member 1'4 which extends with one end 34 beyond the plateshaped portion of the deflecting member 14. The

flange portion 30" is also formed with a plurality of spaced radial openings 28" which are aligned with the openings'28 formed through the bell-shaped member, so that openings-28 and 28 form respectively passages from the inside of the bell-shaped member to the outside of the same;

, Attached to the boss 30' of the deflectingmember, and

, openings 28 and 28'.

For manufacturing purposes and for simplification of assembly. the housing 10 is preferably made of several parts: The housing 10 consists of a top wall of cover part-38 which is formed with a central bore 40 through' which the upper end 26" of the elongated tubular member 26 extends. The cover part 38 has a flange portion 38' and a tubular portion 38" extending in axial direction downwardlyfrom the flange portion 38'. The tubular portion 38" is provided with an external thread which is screwed into an internal thread formed in the upper portion of an intermediate cylindrical housing part 42.

The upper end of this part 42 is also provided with a laterally extending flange 42 and the whole housing may be connected to a frame 43 by clamping this frame between the flange portions 38' and 42. The lower end of the intermediate portion 42 of the tube is also provided with external thread which is screwed into the internal thread provided in the upper end of an intermediate cover 44. This intermediate cover 44 is provided with a central opening 44 through which the upper end of the bell shaped member 12 and the lower end 26' of the elongated tubular member 26 respectively protrude.

The lower end of the intermediate cover 44 is also provided with external screw thread into which the internal screw thread formed in the upper end of the main part 46 of the cylindrical housing is screwed. This part 46 is formed with a bottom wall 46' which is also provided with a central opening 46". This opening 46" is closed on the outside by a bottom cover 48 which is screwed to the bottom wall 46".

A plurality of spaced, small radial bores 50 are formed in the cylindrical main part 46 of the housing located in the same plane as the openings 28 in the bell-shaped member.

The drive means 16 for rotating the bell-shaped member 12 and the parts fixedly attached thereto are shown in the drawings as an elechic motor. The stator 16' of this motor is fixedly attached to the inside of the intermediate cylindrical housing part 42 whereas the rotor 16" is fixedly attached to the outside of the elongated tubular member 26. The member 42 is provided with an opening (not shown) to lead a cable therethrough by which the stator 16' may be connected to a source of power.

Three ball bearings are provided to mount the bellshaped member 12 and the parts fixedly connected thereto for a free rotation about the longitudinal axis. The first ball bearing 52 is mounted in the central opening 40 of the cover plate 38 and connected to the upper end 26" of the elongated tubular member 26, the second ball bearing 54 is mounted in the opening 44' of the intermediate cover part 44 and connected to the lower end 26 of the elongated tubular member, and the third ball bearing 56 is located in the opening 46" provided in the bottom wall 46' of the housing and is connected to the end 34 of the stud shaft. The outer races of all ball bearings are located against shoulders in -the respective housing parts and fixed in their locationby snap rings.

The device described above will operate as follows: The bell-shaped member 12 and the parts fixedly attached thereto are rotated at high speed by the motor 16 about the longitudinal axis of the device. Thereby, the propeller blades 36 and the centrifugal force will create an air stream flowing through the elongated tubular member 26 and through the central opening24 in the upper end 20 of the bell-shaped member, downwardly along the inner surface 18 and willfinally leave the bell-shaped member 12 through the passages formed by the radial openings 28 and 28. If textile fibers are now fed into the bell-mouthed upper end 26" of'the elongated tubular member, these fibers will be sucked in by the air stream through the tubular member 26 until they finally come into contact with the upper semispherical tip 32 of the stem-shaped portion 32 of the deflecting member. The fibers are deflected by this tip 32' towards the inner surface 18 of the bell-shaped member and held in contact with inner surface 18 by the centrifugal force acting on these fibers. passing through the tubular member 26 are thereby twisted and spun into a yarn. Due to the flared shape of the inner surface 18 the centrifugal force acting on the thus spun yarn will create a component acting normal to the surface which keeps the yarn in contact with the surface and a component tangential to the surface which tends to pull the yarn in a downward direction.

member 12.

The finished yarn is taken out of the bell-shaped member 12 through the elongated tubular member 26. The bell-shaped member 12 and the parts fixedly attached thereto are preferably rotated during this time so that the yarn loops are held against the inner surface 18 of the bell-shaped member and are prevented from entangling.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of a centrifugal spinning and winding device for textile fibers differing from the types described above.

While the invention has been illustrated and described as embodied in a spinning and winding device for textile fibers, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
